TM-221A No TX in High Power Due to Voltage Drop 4-11-88
Some TM-221A transceivers may intermittently not transmit in
the high power mode. This condition may be the result of a
voltage drop at the fuse terminals on the power cord. To
prevent a voltage drop, solder the terminals by following
the procedure below.
1. Disconnect the antenna and power supply.
2. Open and remove the plastic fuse holder.
3. Remove the fuse from the terminals.
4. Flow solder between the terminals and the exposed
strands of the cable.
5. Allow the terminals to cool and then reinstall the
fuse and close the holder.
This modification may be covered under warranty.
Time required for this modification is 0.24 hrs or less.
